What is the wavelength of wave if the distance between two consecutive crests is L?
Wavelength (m)=Wave speed (m/s) /Frequency (Hz)
Speed of a wave?
The speed of light, in wave or particle form, travels at approximately 300,000,000 meters per second in a vacuum. Although this speed remains constant, the frequency and wavelength are subject to change. These difference account for various colors of visible light.
What is the wavelength of a sound with a frequency of 20 hertzthe lowest note you can hear as a sound?
The wavelength of a wave is the wave speed divided by the frequency, so you have to know the speed of the wave then divide it by the frquency. You will probably want to change thr frequency to just hz if the speed is m/s, or leave it as khz if the speed is in km/s.
Why is the wavelength of light multiplied by the frequency of light is equal to the speed of light?
v=fλ (velocity (m/s)=frequency (s^-1) * wavelength (m)When dealing with light v=hf is also useful (same derivation as for above), where h is the Planck constant.
Suppose you wish to produce a sound wave that has a wavelength of 8 m in room-temperature air What would its frequency be?
For any wave, the wavelength,l = c/f. Rearranging this, f=c/l. The speed of sound at room temperature is about 300 m/s, so an 8 m wave would have frequency of 300 m/s /8 m =37.5 cycles/s, a little bit lower than the E string on a bass guitar, which is the same as the fifth white key on a piano.
What is the wavelength in a sound wave?
To find the wavelength, the following formula applies: λ = ν / f That in common words is: Wavelength = Wave's Speed / Wave's Frequency So, Wavelength of sound wave = Speed of sound wave / Frequency of sound wave Now, Speed of sound wave is 343 m/s, so Wavelength of sound wave = 343 m/s / Frequency of sound wave Frequency of sound waves audible to a human ear range between 20 Hz to 20 kHz. So filling the desired sound frequency in the equation above you get the desired wavelength of that sound wave.
A sound wave traveling at a speed of 340.0 meters per second has a wavelength of 1.25 what is the frequency?
Answer: frequency = 272 Hz. Given the wave velocity (speed of sound) and wavelength, find the frequency of the wave. Velocity = 340.0 m/s, Wavelength = 1.25 m. Formulas: Velocity = wavelength * frequency. Frequency = velocity / wavelength. Calculation: Frequency = (340.0 m/s) / (1.25 m) = 272 Hz. (Where Hertz = cycles / second.)
What is the speed of a sound wave that has a wavelength of 1.2 m and a frequency of 250 Hz?
300 m/sec
A sound wave produced by a lightning bolt has a frequency of 36 Hz and a wavelength of 12.0 m what is the speed of the sound wave?
Speed = (frequency) x (wavelength) = (36) x (12) = 432 meters per second.Isn't this a pretty high speed for sound in air . . . ? ? ?
What is the speed of a wave that has a wavelength of 10 m and a frequency of 34 hz?
340 m/s
How does the speed of a wave relate to its frequency and wavelength?
Speed of wave (e.g. m/s) = wavelength (m) x number of waves per second (Hz) So you can figure out any one of speed, wavelength or frequency if you know the other two. Often, you know the speed (e.g. light, 3x10^8 m/s, or sound, 340 m/s).
What is the period of a sound wave whose wavelength is 17.0 m?
Divide the speed of sound by the wavelength, to get the frequency. The period is the reciprocal of the frequency. The speed of sound in air is about 343 meters/second, but it depends on temperature. The speed of sound in other materials is quite different from the speed of sound in air.
What it the velocity of a sound wave with a frequency of 425 Hz and a wavelength of 0.75 m?
The speed is (frequency) x (wavelength) = 318.75 meters per second.
What is the wavelength of a water wave that has a frequency of 2.50 Hz and a speed of 4.0 ms?
Wave speed = wavelength x frequency 4.0 m/s = wavelength x 2.50 Hz 1.6 m = wavelength
What is the wavelength of 1KHz?
Wavelength = (speed) / (frequency) If this is a 1 KHz sound wave in air, speed = approx 343 meters/sec Sound wavelength = (343 / 1,000) = 0.343 meter = 34.3 cm If this is a 1 KHz radio wave, speed = approx 300,000,000 meters/sec E & M wavelength = (300,000,000 / 1,000) = 300 Km
What is the speed of a water wave having a wavelength of 2m and a frequency of 0.2hz?
For any wave, the speed of the wave is the product of its frequency and of its wavelength.
What is the wavelength that corresponds to a frequency of 6.00 x 10-14 Hz?
Frequency = 6.00 x 10-14 Hz Wavelength = (speed) /(frequency) -- If this wave is sound in air, then the speed is 343 m/s and the wavelength is 5.72 x 1012 kilometers. -- If this is an electromagnetic wave in vacuum, then the speed is 299,792,458 m/s and the wavelength is 5 x 1018 kilometers.
